Played this game for a few minutes the other day. Biggest surprise: The entire game is co-op? By "certain parts are co-op" I assumed they meant specific minigames. But nope. Like Mario Galaxy's Co-Star mode, a second player can control a second on-screen cursor for Layle's gravity attacks at all times. But, unlike Galaxy, the cursor is actually a pretty significant part of the gameplay.

Also interesting: Sometimes cutscenes transition into minigames with super minimal introduction. You'll basically see a little onscreen thing telling you "Point at the screen" or an icon indicating that you're supposed to shake the remote or use the analog stick. And as soon as you do, that icon goes away. These minigames are almost indistinguishable from cutscenes and are mostly on rails with voice acting and similar camera angles as the cutscenes that precede them. So the long intro cutscene is broken up by a few player-controlled minigames at actiony parts, that blend with the cutscenes seamlessly. Oddly though, there's a fight scene in the intro movie that the player DOESN'T control.

Interestingly, there seems to be no 'lose' state for cutscene minigames. They end with a score or a time, and the goal is to improve that (I'm sure they'll be replayable eventually) but the lack of introduction and possible failure essentially serves to make cutscenes much more engaging.

One of the intro cutscene minigames was two player (Lyle used gravity magic on his machine gun, which is floating behind him, and you us the cursor to aim and fire the gun) and the other was not (using the D-stick to steer a crashing airship while passengers scream dialog at you). There was a little bit of walking around through a mall-like area that served as somewhat of a tutorial for the gravity controls, and then another cutscene minigame happened, this time focusing on the traditional gravity controls but with a camera on rails.

Another weird thing about the game is that in the town area, it's full of NPCs who have simple Chao-like AI, you can't talk to most of them. The only NPC that gave me a "talk" command was Stiltzkin, the traveling Moogle. You can use gravity magic to toss NPCs around the room, but they don't seem to mind or respond. Also, there was a mail Moogle and you could use gravity to yank the letter from him and read it. Sometimes it was a letter intended for you, but sometimes you'll intercept mail intended for others.

I'm going to try to force Dom to play the entire game 2 player, I'm curious to see how it plays that way.
